1996 CHEVROLET EXPRESS radiator

Downloaded from www.Manualslib.com manuals search engine NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn't be covered by your
warranty.
Too much water in the mix can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have
your dealer check your cooling system.
NOTICE:
If you use the proper coolant, you don't have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
Checking Coolant
When your engine is cold, the coolant level should be at
FULL COLD, or a little higher.

If you need more coolant, add the proper mix ut the
coolant recovery tank.
I
L
Turning the radiator pressure cap when the
engine and radiator are hot can allow
steam
and scalding liquids to blow out and burn you
badly. With the coolant recovery tank, you will
almost never have to add coolant at the radiator.
Never turn the radiator pressure cap
-- even a
little 0- when the engine and radiator are hot.
Add coolant mix at the recovery tank, but be careful not
to spill it.
A CAUTION: - -
- , .'.
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Don't spill coolant on
a hot engine.
Radiator Pressure Cap
The radiator pressure cap must be tightly installed with
the arrows
on the cap lined up with the overflow tube on
the radiator filler neck.
I NOTICE:
Your radiator cap is a pressure-type cap and
must be tightly installed to prevent coolant loss
and possible engine damage from overheating. Be
sure the arrows on the cap line up with the
overflow tube on the radiator filler neck.

Downloaded from www.Manualslib.com manuals search engine Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine cooling system. The thermostat stops the
flow
of coolant through the radiator until the coolant
reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat
is recommended.
Power Steering Fluid
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is
a leak in the system or
you hear an unusual noise.
A fluid loss in this system
could indicate
a problem. Have the system inspected
and repaired.
How To Check Power Steering Fluid
When the engine compartment is cool, unscrew the cap
and ,wipe
the dipstick with a clean rag. Replace the cap
and completely tighten it. Then remove the cap again
and look at the fluid level
on the dipstick.
The level should be at the
FULL COLD mark. If
necessary, add only enough fluid to bring the
level up to
the mark.
To prevent brake fluid contamination, never check or fill
the power steering reservoir with the master cylinder
cover off.
What to Use
Refer to the Maintenance Schedule to determine what
kind of fluid
to use. See “Recommended Fluids and
Lubricants’’ in the Index. Always use the proper fluid.
Failure
to use the proper fluid can cause leaks and
damage hoses and seals.

What to Use
When you need windshield washer fluid, b, IP S‘ ure to re
:ad
the manufacturer’s instructions before use.
If you will be
operating your vehicle
in an area where the temperature
may fall below freezing, use a fluid that
has sufficient
protection against freezing.
Adding Washer Fluid
I
Open the cap labeled WASHER FLUID. Add washer
fluid until the tank is full.

When using concentrated washer fluid,
follow the manufacturer’s instructions for
adding water.
Don’t mix water with ready-to-use washer
fluid. Water can cause the solution to fre,eze
and damage your washer fluid tank and
other parts of the washer system. Also,
water doesn’t clean as well
as washer fluid.
Fill your washer fluid tank only
three-quarters full when it’s very cold. This
allows for expansion, which could damage
the tank
if it is completely full.
Don’t use radiator antifreeze in your
windshield washer.
It can damage your
washer system and paint.

Inspections
Listed below are inspections and services which should
be performed at least twice a year (for instance, each
spring and fall). You should let your
GM dealer’s
service department or other qualified service center do
these jobs. Make sure any necessary repairs are
completed at once.
Proper procedures to perform these services may be
found
in a service manual. See “Service and Owner
Publications”
in the Index.
Steering and Suspension Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts, signs
of
wear or lack of lubrication. Inspect the power steering
lines and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body
near the exhaust system.
Look for broken, damaged,
missing or out-of-position parts
as well as open seams,
holes, loose connections or other conditions which could
cause a heat build-up
in the floor pan or could let
exhaust fumes
into the vehicle. See “Engine Exhaust”
in the Index.
Radiator and Heater Hose Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed.
Throttle Linkage Inspection
Inspect the throttle linkage for interference or binding,
and for damage or missing parts. Replace parts as
needed. Replace
any cables that have high effort or
excessive wear. Do not lubricate accelerator and cruise
control cables.
